To all :whom it may concern Be it known'that I, AMBROSE MORASKI, a

citizen of the United States, residing at St.

departing Louis, in the State of Missouri, have invented a new and useful Rotary Internal-Combustion Engine, of which the following is a specification. i

The present invention relates-to improvements in rotary internal combustion engines,

one object of the invention, being the provision of a compact engine of this character, in which the explosive charge is compressed and delivered into a primary combustion chamber and exploded so that the expanding gases therefrom will be directed at the proper time to the piston or pocket of the rotor, such engine being composed of a plurality of such mechanisms and a similar number or in fact any number for reversing the same.

A further object of the present invention is the provision of a combustion chamber sealing means adapted to coiiperate with the rotor to assist in energizing the ignition system at the proper time, the rotor being the timing member to insure the explosion of the compressed charge at the proper time and the delivery of the expanding gas from the combustion chamber to impart movement to the rotor.

A still further object vention is the provision of an adjustable manually controlled means for regulatin the throw of the charge compressing and delivering plunger and consequently the compression of the explosive charge.

With the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the comliination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without from the spirit of the invention.

In the drawings-Figure 1 is a top plan view of an engine constructed according to and embofi ving the present invention. Fig. 2 is a section taken on line 22 of Fig. 1. Figs. 3 and 4 are views on a smaller scale showing the relative position of one rotor after the explosion of the charge and at the exhaust point thereof, respectively. Figs. 5, 6 and 7 are perspective views of the explosion chamber'and the adjacent portion of the present inof the stator. Fig. 8' is a view infelev'atia of the com lete 'ne taken-from wheel and th mg the fly casing, showing the starting mechanism.

lie e designates the base plate of the present engine, which has disposed therein, the member 52, which constitutes a. plurality of rotor chambers-3, one being shown in the present instance. Ad'acent each rotor'chamber 3' and openin rough the outside wall of the stator, a s sown in Fig.7, is the recess 4 Wll10l1,1S adapted tobe sealed by the member 5, clearly shown in detail in Fig. 5. 'An exhaust port 7 is provided in the stator adjacent each rotor chamber thereof, the same exhaustlng into the chamber 7 and through the exhaust pipe E.

A water jacketing space J is provided around the respective rotor chamber carrymg portions of the stator, the plate 8 sealing the uppermost portion thereof while the plate 9 is fitted above the stator portion and fast thereto for carrying the compression mechanism as will presently appear.

The shaft 10 is extended through the stator member of the present engine, and has keyed thereupon within each rotor chamber 3, its respective rotor 11, which isa cam shaped member provided with the radially projecting portion or shelf 12 and with the lip 13 adjacent thereto which is adapted to enga e theperipheral wall of the chamber 3. through the shelf 12 and by means of bolts 15, an adjustable impulse receiving plate 16 is attached thereto. By this means, the outer ends of the plate 16 is adjusted to engage the inner peripheral wall of the chamber 3 and the reduced end 23 of the abutment 20. the detailed structure of which is clearly shown in Fig. 6.

Two shafts 17 and two shafts-17' are journaled for oscillation, one set at opposite points of the upper port on of the stator, as clearly illustrated in Figs. 1 and 2, the shafts 17 constituting the forward rotors controlling shafts, and the shafts 17' constituting the means for assisting in con trolling the reverse rotors (not shown).

The sealing member 5 is provided with the journaling apertured lug 18 which is disposed between the two lugs 19 of the member 20 so that the shaft 17 will enter the apertures of these members and thus aarring tojthe drawings, the numeril '1 11 opening 14 is provided eredf. Fig. 9 is a side eleva of the flywheel and adjacent "portion of% sist in looking the. member 5 in place and at the same time forming a pivoting support for the member 20. The member is pro vided with the rotor engaging end 22 and with the inclined face 21, which is adapted when the member is in the position as shown in Fig. 2, to rest against the inclined face of the transverse lug of the member 5. Thus the chamber 6 is'properly sealed by the member 20 so that the explosive charge introduced therein under pressure will be properly compressed and held against leakage by the cooperation of the rotor 11 with the member 20, and also with the lug 24 and spring 25, which is mounted as shown to return the member 20 from the positions as shown in Figs. 3 and 4 to that shown in Fig. 2.

In order to provide a means for energiz ing the spark plug 37 at the proper time, such action being accomplished by the impulse receiving plate 16 of the r tor 11, a lunger 26 is mounted below the ug 23 of *h'e'l' member 5 and the adjacent portion of he stator and has its stem 27 projected .hrough the bore or aperture 28 of the memer 5 with its outer free end in engagement witlrthe lever 29 fitted in the stem or support 30 attached to the member 5. The spring 31 is connected to the free end of the lever 29 and consequently holds the member or plunger 26 inwardly in engagen'ient with the inclined face 21 of the member 20. This plunger 26 at the proper time, that is when the edge of the plate 16 engages the free end of the member 21, is moved outwardly against the tension of the spring 31, and through the spring 32 imparts inward movement to the member 33 of the lever, so that the free end 35 thereof which is insulated at 34 from the portion 33, engages the terminal 36 of the spark plug 37, as to cause the closure of the circuit in the ignition system and consequently when the parts are in the position as shown in Fig the compressed charge within the chamber 6 will be ignited, and the member 20 mo ed to the position shown in Fig. 3, at hich time the expanding gases will be directed against the piston 16 to cause the rotor to move in the direction of the arrow in Fig. 3 and to finally assume the position as shown in Fig. 4, at which time, the exhausting charge is passing through the port 7 before the space between the free end of the member 20 and the plunger 26 is closed.

Any number of rotors 11 may beemployed so that the proper rotary motion is imparted to the shaft 10 in a steady manner, a fly wheel 69 being attached to the shaft 10 to assist in such action.

Fixed to each end of the shaft 10am riorly of the-stator or casing of the present engine, is a gear 38 which meshes with the intermediate gear 39 and this operates the gear 40 fixed to the shaft 41 and journaled 1n the brackets 42 upon the top plate 9 of the engine. Fixed to the shaft 41 are two eccentrics 43, each one of which operates through the eccentric strap 44, the rod 45, whose opposite end is connected bythe pin 46 to the ower free end of the yoke or cross head carrying member 47. This member 47 is pivoted at 48 to the arm 49 of the bracket 55. Mounted for sliding movement in the cross head carrying member 47, is a cross head or block 50 whichis connected to the piston rod 51 of the explosive charge com-- pressing plunger 52 which is mounted for reciprocation within the cylinder 53. This cylinder 53, as clearly illustrated in Fig. 2, is mounted in the supports 54 and 55 upon the plate 9.

A carbureter C is provided and thus the explosive mixture is drawn in through the pipe 56 into the chamber of the cylinder 53, a check valve being provided to prevent the back flow tliereof. A pipe 57 is also provided with the controlling valve 58, anda check valve 59 directing the charge through the port 60 into the chamber 6. In the present instance, two of the pipes 57 and pumping mechanisms are illustrated.

In order to provide a means for regulating the throw of the piston 52 and conse- 9 quently the amount of the charge and the compressive action thereupon, there is journaled in the arm 61. a shaft 62, provided with two arms 63 one for each of the respective compressing mechanisms. :1 link 64 being connected to each arm and to the block 50, so that said block may be raised or lowered relatively to the member 47' and to the pivoting point 4-8, so that the throw of the rod 51 and piston 52 may be shortened or lengthened as desired. A toothed detent (35 hich is fixed relatively to the arm 61 is pro vided, while an engaging pawl or detent 66 is carried by the handle member of the h-vcr 6 1. Thus the parts may be locked in-thc (lesircd adjusted position.

The reverse combustion charge directive: pipes 57' are controlled through the s mechanism, and by means of the rod ii the cranks 68, the valves of the plirtr; .37 are closed and the pipes 57" are opened. m vice versa, thus permitting the explosi charge forming and compressing members to operate for supplying the charge through either set of the respective pipes 57 or 5 As clearly shown in Figs. 1. 8 and f). til. fly wheel 69 is provided with the two sets oi teeth 70 and 70 which are operated by the respective manually cont-rolled bell crank levers 71 and 72, mounted in brackets 72-- and i.

74. In each bracket 75--75 is -lidably mounted a sleeve76-76, having the pivoted pawl 77-77' in its lower end. The spripg 78 -78. normally holds the pawl 76-76 elevated and out of engagement with the andengaging.

,teeth' -70'. The rod 79-79' is slidably mounted in the'sleeve 76-76 and has the awl engaging end 80-80'; its upper end eing'normally above the top of the sleeve its lever. Thus the pulling upon the lever 71, 'will first cause the rod 79 to move downwardly so that the pawl '17 will be placed to engage one of the teeth 70, the continued movement of the lever pushing the sleeve 76 downwardly and through the pawl imparting a partial revolution to each fly wheel. The same operation of the lever 72 imparts a reverse rotation to the fly wheel.
